In the dry etching process using fluorocarbon (FC) gas, deposited amorphous-CF x (a-CF x ) films in patterns, such as holes and trenches, strongly affect the etching performance. The influence of the FC gas molecular structures and their atomic compo

Angular distributions of high energy neutrals and ions, impinging on a RF-biased electrode in a 13.56 MHz capacitively-coupled argon plasma were investigated. Ions and neutrals were introduced into a drift chamber that was directly connected to the R

C2F4 is a potential etching gas for high aspect ratio etching of SiO2 films owing to its high etch rate. However, it is difficult to fill C2F4 to a gas cylinder with high pressure for mass production due to its high reactivity. To overcome this probl

On-site C2F4 gas production from CF4 feedstock gas was achieved using pure CF4 plasma at a moderate pressure (40–200 Torr) and a relatively low gas temperature. The decomposition of CF4 and the generation of perfluorocarbon gases with a larger numb

Charging and discharging behavior of high aspect-ratio (AR) hole capillary plate (CP) exposed to a pulse-modulated very high frequency (VHF) capacitively-coupled plasma is investigated. From an equivalent circuit model, time-dependent charge density

Absolute values of the surface charge densities at the top and bottom of a capillary plate (CP) placed on a powered electrode were evaluated under the influence of pulse-modulated very high frequency (40 MHz) plasma. The peak-to-peak voltage at the t

The initial stage of Al2O3 films deposited by atomic layer deposition (ALD) on a H-terminated Si(001) wafer was investigated with in situ X-ray photoelectron spectroscopy (XPS). At deposition temperatures of 250 °C and 300 °C, no Al peak was detect

The atomic layer etching (ALE) characteristics of AlGaN using Cl2 plasma in the modification step and Ar plasma in the removal step were investigated in comparison with conventional reactive ion etching (RIE). Although surface roughening and GaN comp

Tunneling barrier height (BH) has been measured at two types of surface defects on Si(001), the type-C defect and the split-off-dimer defect. Contrary to previous experiments, we find no evidence of large BH reduction at these defect sites. For both

We have carried out barrier-height imaging on clean Si(001) 2 ×1 and Ni-contaminated 2 ×n surfaces and investigated the local barrier-height variation at and around Ni-related dimer-vacancy (DV) defects which are referred to as (1+2)-DVs. The barri
